WEEK 12 – SEALANTS EXAM
QUESTIONS WITH CORRECT
ANSWERS
Dental Sealants Summary - Correct Answers -- act as a physical barrier to bacteria
- non-invasive
- Success is dependant on adherence/retention of the resin material
Preventive Sealants: - Correct Answers -are those placed in caries-free teeth in an
effort to prevent dental caries. Primary Prevention strategy.
Light-Cured (Photopolymerized) - Correct Answers -- Harden with restorative curing
light
- Because no mixing is required, the clinician controls the start of polymerization
- Infection control is a consideration for the equipment used for this process
- Curing light tip should either be sterilized or used with a plastic barrier (must not
decrease the intensity of the light beam)
- Curing light 10-20 seconds.
Autopolymerized sealants cure/shrink - Correct Answers -toward the center of the
material and provide a good sealant to tooth margins
Therapeutic Sealants: - Correct Answers -are those placed in teeth with incipient lesions
in an effort to arrest the decay process. Secondary Prevention strategy.
Indications for Sealant Placement - Correct Answers -- Deep plaque-retentive pits and
fissures on the occlusal surfaces of the teeth
- Incipient caries and no radiographic evidence of caries on the proximal surface
- Xerostomia
- Orthodontic appliances or bands
Need for head/neck radiation therapy
- Infrequent professional preventive care
- High caries experience/visible heavy plaque
